'lO ALL-WHOM IT MAY CONOERN:

Be it known that I, J. DEAN I-IUFFMAN, of Springfield, `in the county of Clark, and State of Ohio, have invented a new and useful Improvement in Stump-Fullers and Grubbers; and I do hereby declare that the following is a full, clear, landexact description of the same, reference being had to the annexed drawings, making part of this specification, inwhich- Eigure l is a side elevation g and Figure 2 is an end elevation.

The same 'letters in both gures are used 4in the indication of parts, which are identical.

The red lines in lig. 1 indicate the actionAv of the machine.

A is the lever, which is va strong' beam, t0 which the draught is applied at the upper end. The lower end is securely fastened into a notchcut in the cylindrical fulcrum B, which rests upon the ground, and supports the lever when in a. vertical position. The-wheels C are attached to the cylindrical fulcrum by journals or axles, which are secured to and pass through the cylinder, projecting therefrom eccentrically'at such point that. when the lever is verticalthe whole weight rests upon the cylindrical fulcrnm, but when the lever is horizontal, as Shown by the red lines on iig. 1, the Weight rests upon the wheel C, which may noiv be used to draw the stump-puller from place to place. D is the extension hook, formed substantially as shown in fig. 1. It has inclined notches cut at intervals in its loweredge, so that'it may belattached to the lever in such manuel that it may-be adjusted to -the size of the stump over the top of which it passes, the pointed hook entering the stump. The hook is ilaton top so as to give it bearing against the Wood, and should bev increased in thickness at the point for this purpose as well as to strengthen it where it diminishes in diameter.

A slot, A1, is cut through the lever to receive the extension hook, which is fastened by the notches to the stirrup E` a. strong rod attached to the cylinder B in front'and carried around the lever. An iron plate, A2, formed in one piece is attached'on the 'front of the lever at'the lower end, having a projecting edge or bite at A3. The stump-puller is also attached to the stump by chains Il'. These chains are secured to eyes G, fastened to the cylinder B, and are Wrapped around the stump, and fastened by wedges driven into the stump. The lever should rest upon a solid block of wood, its lower endvbeingbevelled to prevent the corner forming a fulerum.

The extension hook being attached to the stump, and the chains F secured, the power is applied at the top of the lever, and the stump drawn from the ground, as shown in fig. I. The extension hook and chains are designed to be used in extracting the large stumps; instead of these I use the clevis a: for pullingthe smaller saplings. The elevis is a bent rod, with hooks at each end, \rhich are to be hooked over the stirrup E, the clevis encircling the grub' to be pulled up. The action of the machine is the same where the clevis is used as where the extension hook and ehainssare employed.

What I claim as my invention, and desire to secure by Letters Patent, lis

1. The lever A of a. stump-puller, in combination with the cylindrical fulcrum B, supporting the wheel C eccentrically attached thereto, substantially in the manner and for the purpose set forth.

2. In combination with the slotted lever A, eccentrically attached, the fixed cylindrical fulcruni'B, adjust-- able extension Vhook D, and stirrnp E, when constructed and arranged substantially as setforth.

3. 'Ihe arrangement of the slotted lever A with the plate A2 and bite A3, adjustable extension hook D., and chains I", and eccentrieally-attached, xed cylindrical fulcruni B, substantially as set forth.

4. In combination with the lever A,.eccentrically-attached fixed cylindrical fulcrum B, and stirrup E, I claim the hooked clevis 1*, substantially as and for the purpose set forth.

In testimony whereof I have signed m'y name-to this specification in the presence of two subscribing witnesses.
